Which Xferoption should be selected and should we use both functions ie

HAL_StatusTypeDef HAL_SMBUS_Master_Transmit_IT(SMBUS_HandleTypeDef *hsmbus, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t XferOptions)

and

HAL_StatusTypeDef HAL_SMBUS_Master_Receive_IT(SMBUS_HandleTypeDef *hsmbus, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t XferOptions)

to implement read block protocol.

The same question for slave also?
